The invention relates to printing devices for use in connection with business machines and, more particularly, for printing characters such as number indications of a counting mechanism.

In a known printing device or" this type the wiping device is moved in the main radially relative to the striking device. Consequently the difference between the smallest and the largest range of the striking device is equal to the greatest distance over which the typebearer can be moved.

Apart from the great range of the striking device, moreover, the drawback originates that the wiping device by its movement radially relative to the striking device, which movement takes place in the shifting direction or" the typebearcr, requires a large construction length.

The invention tries to eliminate these drawbacks and to provide a material reduction of the structure in the shifting direction of the typebearer. This is mainly obtained because strokes of the striking device that belong to the separate figure values have been provided at angular distances of various magnitude, each of which stroke co-operates with one of a number of stages of the wiping device. The construction according 'to the invention has the advantage that the movement of the wiping device, the way length of which of course is also determined by the greatest shift of the typebearer, is effected not radially but tangentially, respectively, in the direction of a cord relative to the centre of the striking device. So the wiping device can be lifted, respectively shifted into the centre line of the counting device or even higher.

The drawing shows an embodiment of the invention. Fig. 1 shows the printing device in the normal position. Figs. 2-10 represent the wiping device and the striking device in the positions appropriate to the separate figure values.

The type carrier I, slidably mounted in stationary guides 2, can be shifted in vertical direction and carries a stepped plate 3 equipped with six steps. The typecarrier l during the first part of each operation is released'for its upward shift by some known driving mechanism, which returns the typecarrier to its normal position during the second part of its operation. The upward movement of the typecarrier I can e. gbe effected by a spring, which may be attached to a cam associated with the stepped plate 3; The plate 3 co-operates with a control member 4, which is connected to a counter wheel (not shown in the drawing) of the counting device. Further the counting wheel is connected to a locking or ratchet wheel 6 having co-operating therewith a pawl I. The control member 4 has nine outwardly extending teeth whose radial .distance from the axis of rotation of the member 4 varies while the teeth are placed relative to each other at different angular distances. These teeth are provided in the drawings with the figures 0,1 to 8, while the individual steps of plate 3 are designated with the same numerals in such a manner that each individual step carries the number or numbers of the tooth or teeth of member 4 with which the respective step co-operates. Thus, for example, the uppermost step of plate 3 carries the numbers 1, 2 and 3 because this step co-operates with teeth 1, 2 and 3 of member 4. Finally a stationary abutment ID has been provided against which the plate 3 abuts when the type carrier l is positioned corresponding to the figure value 9.

The method of operation of the described printing device will be obvious from the drawing. It may be observed that the sides of the various teeth of the control member 4 may be so shaped that in co-operation with the stages of the plate 3 the movement of the control member 4 will be limited automatically and the pawl l and the pawl 6 may optionally be omitted. In the represented embodiment such an automatic limitation e. g. originates for the figure values 0-8 as will appear from the figures.
